Application of plastic design in steel table shelters
One of the initial applications of plastic theory of structures was the Morrison Shelter, an indoor air raid shelter designed by John Fleetwood Baker (1901 - 1985) during the Second World War to protect British civilians from unrelenting German air raids. Baker integrated his previous work on …

Growing Things: An Investigation in the ways that plant-growth may inform the process of painting
… traditional Western landscape painting in light of the contemporary understanding that ‘nature’ has been rearticulated, even plasticised and hence rendered malleable, through human action. The idea of a plasticised natural environment is concomitant with the age of the Anthropocene which has …

High-throughput Photodegradation of Plastics
Plastic is a critical resource in the modern world, but an emphasis on durability in design coupled with the widespread use of plastic products has led to significant accumulation of plastic waste in the environment. It is imperative that new chemistries are discovered to produce polymers with the …

Benthic invertebrate management in plastic-lined fish culture ponds
<p>The use of plastic-lined ponds in place of earthen ponds for fish culture is becoming common among agencies; however limited information is available on their management. Since plastic lining significantly reduces the amount of organic sediment typically found on the bottom of culture ponds …

Laboratory investigation of soil reinforcement using shredded waste plastic bottles
Plastic bottles were first used commercially in 1947 but remained relatively expensive until the early 1960s when high-density polyethylene was introduced, with its attractive characteristics such as being strong, lightweight, durable, cheap, and resistance to breakage. Decomposition of plastic …
